For Such A Time As This, Esther 4, OT S1:E271

Mordecai pleads with Esther to intervene on behalf of her people, who are faced with extermination at the hands of Haman. She is torn. She wants to help, but isn't feeling the love of the king, and could experience the same fate as Vashti if she overplays her hand. By risking her life and position to address the king, she is a type of Christ, and wisely seeks the king's favor before making her entreaty.
